To enter
Build a billion dollar company's product in a couple of days.
ZoomInfo and Clay are billion dollar companies. Underneath, they are data, workflows, and outreach with an interface on top, and every customer gets the same product.
graph8 already runs all of that in one backend: 700M contacts, enrichment, signals, sequences, a dialer and phone numbers, landing pages, LinkedIn touches, inbox, and CRM. We handle the hard parts: the data, the deliverability, the telephony, the hosting.
You decide exactly what the app does for your team or for each client, and build it with your own Claude, Codex, or ChatGPT connected to graph8. graph8 deploys it as an application with your brand and your name on it.

Think it
Describe what your team or your client needs. The prospecting app, the client portal, the call cockpit, the report nobody has time to build.
Build it
Connect the graph8 programmable revenue engine over the MCP server to the tool you already use. Coding experts build in Claude Code, Codex, Cursor, VS Code, Antigravity, or your terminal. Everyone else describes it in plain English in the Claude or ChatGPT desktop app. The agent writes the code. graph8 wires it to the backend and deploys it under your brand, for your team or your clients.
Everything a revenue team runs on is already in the backend.
Your app calls it. You never set up a data vendor, a phone carrier, a mail server, or a host.
700M contacts, 100M companies
Search free, with waterfall enrichment for emails and phones
Signals and intent
30B buyer signals a month, website visitors, job changes
Sequences
Email, SMS, WhatsApp, and call steps, with LinkedIn touches
Dialer and telephony
Dial four lines at once, meetings booked on the call. Numbers are included, paid from your credits
Landing pages
Drafted with AI, published on brand, forms that route the lead
Inbox and web chat
Every reply and chat in one place, sorted and drafted
Appointments
Booking pages, round robins, reminders
CRM and quotes
Deals, pipeline, and quotes that send
AI agents
Agents that research, draft, call, and follow up
API, SDK, MCP, CLI
300+ endpoints and 500+ MCP tools, for the engineers who want them
MCP Unlimited is free for every registered builder until 30 November. After that, your app keeps running on a graph8 build plan, and an agency can give each client its own org. The plans and rates are on build pricing.

Questions
Do I need to know how to code?
No. Connect graph8 to the Claude or ChatGPT desktop app over the MCP server and describe what you want in plain English. The agent writes the code. Office hours every Tuesday help you get unstuck, and there is a prize for the best build by a non engineer.
What do I need to bring?
A free graph8 account and your own Claude, Codex, or ChatGPT account, or any IDE. The data, the dialer, the hosting, and the deployment are on graph8.
How does it run?
Register now. Building starts at the kickoff on Monday 5 October, 12:00 ET, and runs for two weeks, until Sunday 18 October at 23:59 ET. The judges review every submission and name the finalists on Wednesday 21 October, and the finalists present live on Sunday 25 October.
How big can a team be?
Any size. Solo, a pair, an agency, or a whole SDR team. Prizes go to the team.
I already built something on graph8. Can I enter it?
Yes. Enter it and show what you added during the hackathon. Post it now too. It earns credits.
Whose brand is on the app?
Yours. Name it, brand it, run your team on it, build it for your clients, or sell it. You own it. graph8 may show it with credit.
Can I build a version for each of my clients?
Yes. Shape the app to what each client needs, and run each client in its own org.
What does it cost to run my app after the hackathon?
Your app keeps running on a graph8 build plan. The plans, the usage rates, and the one org per client for agencies are on graph8 build pricing.
Can I sell an app that shows graph8 data?
Yes. Your app can show and act on graph8 data for your team or your clients. Exporting or reselling the database itself is not allowed.
How do the $20,000+ in prizes add up?
$1,750 of it is cash: $1,000, $500, and $250 for the top three. The rest is 12 and 6 month graph8 Team plans and execution credits, counted at list price. The full breakdown is in the prizes section. MCP Unlimited for every builder comes on top.
How do the credits for posting work?
Add your LinkedIn, X, Instagram, and TikTok accounts when you register. Post, tag graph8, and use #graph8build. We track the posts and add the credits to your graph8 account within two business days, until the 140,000 credit pool runs out.
Does it cost anything?
No. Entering, the account, and MCP Unlimited until 30 November are free. Nothing converts to a paid plan on its own.
What do I submit?
By Sunday 18 October at 23:59 ET: a link to your app and a video of three minutes or less that shows it working. If you are a finalist, your presentation slot arrives by email.
Can I send real emails and calls while I build?
Only to people who expect them, from your own domain.
